Santos was incorporated on 18 March 1954, with its name an acronym of South Australia Northern Territory Oil Search. Its core business was initially built on gas discoveries in the Cooper Basin, South Australia, with the discovery and development of the Gidgealpa 2 well in 1963 and Moomba 1 in 1966. It signed supply contracts with the South Australian Gas Company, the Electricity Trust of South Australia and the Australian Gas Light Company, commencing supply in 1969.After oil was discovered at Tirrawarra, near Moomba, South Australia, in the early 1970s, the company developed its liquid supply operations, which included a plant at Moomba and a fractionation and loading facility at Port Bonython.In the 1990s, the company expanded, acquiring other companies and developing its operations both onshore and offshore in Australia, Indonesia, Malaysia, Vietnam and Papua New Guinea. Also in this decade it acquired interests in petroleum in the United States and United Kingdom, as well as operations in the Timor Sea and Western Australia. The Ballera gas plant in South West Queensland was established in 1991 and upgraded in 1997.In 2015 Santos began producing LNG, shipping it to South Korea.

In August 2018 Santos announced the acquisition of Australian oil and gas company Quadrant Energy for $2.15 billion. As part of the deal, Santos obtained Quadrant's 80% stake in Dorado in the Bedout Basin in northern Western Australia.In May 2020 Santos completed its acquisition of ConocoPhillips' northern Australia and Timor-Leste assets for US$1.265 billion as well as a contingent payment of US$200 million, which gave Santos control of ageing offshore assets in Bayu-Undan, subsea assets in the Timor Sea, and onshore gas plant Darwin LNG , which included the Bayu-Undan to Darwin Pipeline. At the completion of the deal with ConocoPhillips, the interest of Santos in these assets was increased to 68.4%, The sale was contingent on a final investment decision on the future #Barossa project, which once concluded increased Santos' interest in the project to 62.5%.
